Not really sure what you are referring to as OBD 1.5, but as long as the engine from the 95 you put in is TBI and everything plugs in, shouldn't be a problem.Hi I have a 93 Z-71 stepside with 260K on 5.7. I just bought and installed a 95 5.7 out of a clean 135K truck. I have run into a few differences like the 95 water pump had barb for heater hose. My question is concerning the computer, will I need to do anything because of the OBD 1 and OBD 1.5 differences? Please keep responses simple as I am not a computer geek. Thanks for any input, plan on firing the engine tomorrow. Mac
